nextUp() float in Java

nextUp(): This method is available in the Math class of Java.

Syntax:

float java.lang.Math.nextUp(float f)

This method takes one argument of type float as its parameter. This method returns the floating-point value adjacent to f in the direction of positive infinity.

Special Cases:

1. If the argument is NaN, the result is NaN.

2. If the argument is positive infinity, the result is positive infinity.

3. If the argument is zero, the result is Float.MIN_VALUE.

Parameters: One parameter is required for this method.

f: starting floating-point value.

Returns: The adjacent floating-point value closer to positive infinity.

For Example:

Math.nextUp(19.9)  = > It returns 19.900002

Approach

Java

public class NextUpFloat {
    public static void main(String[] args) {

        float f = (float) 19.9;
        System.out.println(Math.nextUp(f));

    }
}

Output:

19.900002
